LAMP-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 450,410, dated April14, 1891.

Application tiled January 15, 1889. Serial No. 296,430. (No model.)Patented in Belgium October l5, 1888, No. 83,370.

To all whom t may concern:

Be it known that I, ANDREAS GULBRAND- SEN HOvDE, a subject of the Kingof Norway, and a resident of IfIoenefos, in the Kingdom of Norway, haveinvented a new and useful Improvement in Lamp-Extinguishers, (for-whichI have obtained Letters Patent in Belgium,

No. 83,370, dated October 15, 1888;) and I do hereby declare that thefollowing is a full, clear, and exact description of the same.

This invention relates to lamp-burners in which a round disk is employedabove the round-wick tube to spread the flame and give it a more or lessspherical form, and particularly relates to the means whereby the diskmay easily be lowered down upon the wick or the wick-tube and therebycause the flame to be extinguished. This lowering down of thellame-spreading disk is effected by a part having an inclined surface,such as a cam or wedge, upon which the support of the disk, under whichthe said part is situated, rests by gravity, thereby simplifying theconstruction and materially decreasing the cost of manufacture withoutimpairing the efficiency of the apparatus. When arranging the same insuch manner, the ,lamp-burners may be utilized in their present shapewithout undergoing other alterations than having a few slots cut in themor the like.

In the annexed drawings are shown two forms of the saidlamp-extinguishing device embodying the principle of the invention.

In both cases the disk falls down by its own weight as soon asadevicehaving the inclined surface that keeps the same in appropriate positionabove the Wick has been moved away. This device is a wedge in one or theother form. The employment of a Wedge is preferably used, as it greatlyfacilitates the elevating of the disk to its ordinary position when thelamp is burning.

In Figure l is shown a lamp-burner of the said description, and wherethe above-mentioned disk has sufficient diameter to cover the wick whenlowered down upon it. The

disk D is fastened on top of tube CZ, sliding within a tube t in thecenter of the burner.` When in its elevated position the bottom of tubed rests on the horizontal part of a 5o plate p, inserted from outsideinto the burner and outside provided with a handleh of some preferableshape. The inner end p of this plate is wedge-shaped, and it is easilyseen that when the plate is drawn outward so that the point of the wedgehas passed the tube t the tube, and with this the disk, will drop down,the disk D thereby putting out the flame. In Fig. 2 the same result isattained by a wedgeshaped or eccentric disk P, mounted on a spindle p',outside provided with a handle h. In both cases the diskD again will beraised by moving the handle h h in reverse direction of what was donewhen extinguishing the llame.

To avoid smell4 from the wick, the same should always be turned down alittle before being extinguished.

vW'hat I claim as new, and desire to secure by Letters Patent, is-- l.Alamp regulating and extinguishing device consisting of the combination,with the wick-tube, of a disk of greater diameter than the wick-tube andhaving a support, a guide therefor, a movable part situated directlyunder the disk-support and having an inclined surface, and anoperating-handle for moving said part to cause its inclined surface toslide upon the under face of said support, substantially as set forth.

2. A lamp-extinguishing device substan-. tially consisting of a circulardisk of greater diameter than the wick-tube, a tube or pin on which itis mounted, a tube serving as a guide for the latter, and a wedgearranged below the same.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

ANDREAS GULBRANDSEN HOVDE.
